QUE 1

Consider the following .

The tableau corresponds with a step of the SIMPLEX

method applied to the previous problem.

- What is the value of the variables and the objective function?

- Identify the entering and

the leaving variables. Justify your response with the calculations performed

(you can extend the previous tableau to perform the required calculations)

Entering Variable: Leaving Variable: |

- Based

on the information summarized in the sensitivity report of Excel (corresponding

to the optimal solution, answer the following questions.

- How it affected the value

of objective function if the right side of the third constraint increase in 2

units? Justify

with the calculations performed

- How many units is possible

to increase the right side of the third constraint without losing the geometry

of the current optimal solution

Que 2.

The ABC

Company is planning to replace its current electrical infrastructure with a new

special system. Since the new system has more capacity it is not necessary to

maintain all the current connections. The manager wishes to decide which pairs

of offices should be directly connected in order to ensure that every office is

connected (directly or indirectly) in the new system. The figure shows the

current infrastructure: the letters represent the offices and the arcs, the

connections. The numbers represent the distances between the corresponding

nodes.

In order to minimize the cost: What are the

offices that must be directly connected? Assuming that for the new system is

required 3 units of cable for each unit of distance, how many units of cable

should be purchased by the company? Justify with the calculations performed.

- Is this problem
**P**or**NP**? Justify

Que 3.

The town hall of a city wants to open some

recreational centers. It has been analyzed 3 options. The opening cost and the

capacity of each center are listed below.

The

selected recreational centers must be hosting the students from 5 schools. In

the table below is summarized the number of students at each school.

Each

school must be assigned to only one recreational center. And the capacity of

each center must be respected. What are the recreational centers that must be

open in order to minimize the opening cost?

- Formulated a mathematical programming model. (Linear

Model is required) - Modify the previous model such that are considered the

following constraints: - One school can be assigned to several recreation

centers - It is decided to open at most two recreation-center
- Design a greedy solution strategy for the problem

described in 1. - Illustrate the greedy procedure with the following

data:

Que 4.

Answer the

following questions:

**What is a**

flow-oriented simulation software (such as FlexSim) used for?**Explain why simulation software’s are**

used?

Answer the

following questions related to FlexSim software:

**The main resources found in any simulation**

model are source, queue, processor and sink. Briefly explain the role of each.**Which kind of connection may be used to**

connect the above-mentioned resources?**What does the “machine**

throughput” measure?
